Urea Plus Nitrate Pretreatment of Straws Enhances Degradation and Reduces Methane Production[Apr 26, 2018]

A research team led by ZHANG Xiumin from the Institute of Subtropical Agriculture pretreated rice and wheat straws by urea plus nitrate (urea+nitrate) together to improve the degradation of straws and reduce the CH4 production from ruminants. They found that urea+nitrate pretreatment can destroy the physical structure of straws, increase the neutral-detergent soluble content that degrades easily and fast in the rumen, and increase the in vitro degradation of both straws.

How Does Urban-induced Warming in Beijing Interact with Air Temperature in Summer?[Apr 26, 2018]

Scientists from Beijing Normal University and the Institute of Atmospheric Physics used the mesoscale weather research and forecasting model coupled with a single urban canopy model and high-resolution land cover data to analyze the spatial and temporal patterns of summertime urban warming influenced by three stages of urban land expansion during 1990-2010 across Beijing.

Scientists Reveal Hydrochemical Characteristics of Ground Ice in the Qinghai-Tibet Plateau[Apr 25, 2018]

Recently, scientists from the Northwest Institute of Eco-Environment and Resources, together with their colleagues, analyzed the spatial variations and controls of ground ice hydrochemistry in permafrost regions on the Qinghai-Tibet Plateau using data from nine soil profiles, and systematically illustrated the sources and the moisture and salt migration of ground ice in the context of permafrost degradation.

Scientists Reveal Mechanism and Predictor of Clinical Efficacy of Psychosurgery in Severe Obsessive-compulsive Disorder[Apr 25, 2018]

Obsessive-compulsive disorder (OCD) is a debilitating and chronic disorder. The researchers from the Institute of Neuroscience of Chinese Academy of Sciences, and Shanghai Jiao Tong University Medical School Affiliated Ruijin Hospital, used resting-state functional magnetic resonance imaging (fMRI) to investigate neural mechanism and response variability underlying neurosurgical interventions for severe OCD. They revealed that two dissociable frontostriatal circuits underlie mechanism and predictor of the clinical efficacy of capsulotomy.

Environmental Factors Affect Geographic Patterns of Leaf and Seed Traits of a Relict Tree Species[Apr 25, 2018]

Supervised by Prof. JIANG Mingxi and Prof. WEI Xinzeng, a research team from Wuhan Botanical Garden collected leaf and seed traits of Euptelea pleiospermum across its natural distribution in China. They measured 13 leaf traits and nine seed traits, and analyzed their geographic patterns and environmental drivers.

Study: Social Mistrust is Heritable in Chinese Children and Adolescents[Apr 24, 2018]

To resolve the questions mentioned above, Dr. Raymond Chan's team from the Neuropsychology and Applied Cognitive Neuroscience Laboratory, together with his international collaborators, has carried out a large cross-sectional survey of 8 to 14 year-old Chinese twins, using a new dimensional measure of childhood suspiciousness: the Social Mistrust Scale (SMS).
